Changes of length of connection path in packet EIP_OBJECT_FWD_OPEN_FWD_RES leads to rejection of the incoming connection with error code 0x13 (Not enough data) or 0x15 (Too much data)

The host application has the possiblity to receive the whole forward open frame using the indication (EIP_OBJECT_FWD_OPEN_FWD_IND - 0x1A4A). The host application then can change the connection path before sending it back to the stack. In case the length of the connection path changes, the stack does not handle the connection path properly and sets the general error 0x13/0x15 in the forward open response frame on the network.
